Some folks use an old A/C condenser--I may put one on my diesel truck--the cooler thats on there now is a dinky little joke,looks more like a power steering cooler,so I might hook it up to the P/S instead,after removing it from the radiator core,I hate those nylon "poke thru the radiator"things they give you to hold it on with--who invented those retarded things--the modine replacement radiator company??.They do a nice job of sawing the tubes in your radiator in half. /forums/images/graemlins/angryfire.gif Not good when its nearly 400 bucks for a new 6.2 radiator. /forums/images/graemlins/yikes.gif /forums/images/graemlins/eek.gif
